VS C＃与VB中的可变范围

Question

I have a solution with 2 projects - 1 VB, 1 C#. I want to see and edit a global variable of my VB project from my C# project. I have declared the string variable (in VB) as Public Shared.

I can't see it from my C# project.

I am not familiar with C#, so I am not sure how to do the equivalent of an 'Imports' statement to get visibility of my VB project and its global variable. Can I do this? Or am I not really thinking this through correctly? (I am a VB guy, so C# is a bit of a mystery still). Thanks.

Answer 1

Neither VB nor C# supports global variables.

You need to add a reference to the VB project from the C# project so that it can use its members.
You can then access the static field / property of the class / module that you declared it in:

ClassName.PropertyName

Answer 2

While VB supports module-level declares, C# does not. In C#, a VB module would appear as a static class. In VB you can also import entire classes and use their shared/static members globally. This is also not something that can be achieved in C#.

If, in VB, you have:

Public Module MyDeclares

    Public MyGlobalString As String

End Module

Then in C#, you would add a reference to that project, and then code like this:

using MyProject;

and access the field:

MyDeclares.MyGlobalString = "Some text";

EDITED If you want to access properties and methods in another assembly that are declared internal (friend in VB) then you would modify your AssemblyInfo.vb (or AssemblyInfo.cs) file and add an InternalsVisibleTo declaration to the assembly that you want to expose, referencing the assembly (not the namespace) that you want to allow access for.

If your assembly uses strong key signing you will have to include the public key in the definition. Follow the link for more information including examples.

Answer 3

我最终将我的模块留在了VB项目中，那是我可以在各个部分中获得良好可见性的唯一方法。
